A Boeing 747

Aviation includes the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships.

Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. (Full article...)

A helicopter is a type of rotorcraft in which lift and thrust are supplied by one or more engine driven rotors. In contrast with fixed-wing aircraft, this allows the helicopter to take off and land vertically, to hover, and to fly forwards, backwards and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft would not be able to take off or land. The capability to efficiently hover for extended periods of time allows a helicopter to accomplish tasks that fixed-wing aircraft and other forms of vertical takeoff and landing aircraft cannot perform.

The word 'helicopter' is adapted from the French hélicoptère, coined by Gustave de Ponton d'Amecourt in 1861, which originates from the Greek helix/helik- (ἕλικ-) = 'spiral' or 'turning' and pteron (πτερόν) = 'wing'.

Helicopters were developed and built during the first half-century of flight, with some reaching limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it was the single main rotor with antitorque tail rotor configuration of this design that would come to be recognized worldwide as the helicopter.

Selected biography

Erich Alfred "Bubi" Hartmann (19 April 1922 – 20 September 1993), also nicknamed "The Blond Knight of Germany" by friends and "The Black Devil" by his enemies, was a German fighter pilot and still is the highest scoring fighter ace in the history of aerial combat. He scored 352 aerial victories (of which 345 were won against the Soviet Air Force, and 260 of which were fighters) in 1,404 combat missions and engaging in aerial combat 825 times while serving with the Luftwaffe in World War II. During the course of his career Hartmann was forced to crash land his damaged fighter 14 times. This was due to damage received from parts of enemy aircraft he had just shot down, or mechanical failure. Hartmann was never shot down or forced to land due to enemy fire.[1]

Hartmann, a pre-war glider pilot, joined the Luftwaffe in 1940 and completed his fighter pilot training in 1942. He was posted to Jagdgeschwader 52 (JG 52) on the Eastern front and was fortunate to be placed under the supervision of some of the Luftwaffe's most experienced fighter pilots. Under their guidance Hartmann steadily developed his tactics which would earn him the coveted Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds on 25 August 1944 for claiming 301 aerial victories.

He scored his 352nd and last aerial victory on 8 May 1945. He and the remainder of JG 52 surrendered to United States Army forces and were turned over to the Red Army. Convicted of false "War Crimes" and sentenced to 25 years of hard labour, Hartmann would spend 10 years in various Soviet prison camps and gulags until he was released in 1955. In 1956, Hartmann joined the newly established West German Luftwaffe and became the first Geschwaderkommodore of Jagdgeschwader 71 "Richthofen". Hartmann resigned early from the Bundeswehr in 1970, largely due to his opposition of the F-104 Starfighter deployment in the Bundesluftwaffe and the resulting clashes with his superiors over this issue. Erich Hartmann died in 1993.

Selected Aircraft

The Boeing 777 is a long-range, wide-body twin-engine jet airliner manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet and is commonly referred to as the "Triple Seven". The aircraft has seating for over 300 passengers and has a range from 5,235 to 9,380 nautical miles (9,695 to 17,372 km) depending on model. Its distinguishing features include the largest diameter turbofan engines of any aircraft, six wheels on each main landing gear, a circular fuselage cross-section, and blade-shaped tail cone. Developed in consultation with eight major airlines, the 777 was designed to replace older wide-body airliners and bridge the capacity difference between the 767 and 747. As Boeing's first fly-by-wire airliner, it has computer mediated controls; it is also the first entirely computer-designed commercial aircraft.

The 777 is produced in two fuselage lengths. The original 777-200 model first entered service in 1995, followed by the extended range 777-200ER in 1997; the stretched 777-300, which is 33.3 ft (10.1 m) longer, began service in 1998. The longer-range 777-300ER and 777-200LR variants entered service in 2004 and 2006, respectively, while a freighter version, the 777F, debuted in 2008. Both longer-range versions and the freighter feature General Electric GE90 engines, as well as extended and raked wingtips. Other models are equipped with either the GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800 engines. The 777-200LR ranks as the world's longest-range airliner and holds the record for longest distance flown by an unrefuelled commercial aircraft, with the demonstrated capability to fly more than halfway around the world.

United Airlines first placed the 777 into commercial airline service in 1995. As of August 2023, 1,716 777s have been delivered. The most common variant used worldwide is the 777-300ER, with 832 aircraft delivered, and Emirates operates the largest 777 fleet, with 134 aircraft (as of May 2019). The airliner has had 8 hull-loss accidents, with 541 fatalities. The most deadly incident was Malaysia Airlines Flight 17, in which a 777-200ER carrying 298 people was shot down by a missile over Ukraine on 17 July 2014.

Through the 21st century, the 777 has emerged as one of its manufacturer's best-selling models. Because of rising fuel costs, airlines have acquired the type as a comparatively fuel-efficient alternative to other wide-body jets and have increasingly used the aircraft on long-haul, transoceanic routes. Direct market competitors include the Airbus A330-300, the A340 and A350 XWB.
